Definitions

  • the invention relates to a device for producing a circular-cylindrical breakthrough in a wall, in particular masonry wall, - with a hollow boring tool which has a drill bit formed by cutting teeth at the free end of a drill sleeve and is drivable by a rotary drill.
  • the drill sleeve also has a limited length, so that after reaching a certain drilling depth interrupted drilling, the hollow boring tool retracted, the stalled hollow cylindrical core must be destroyed and removed, whereupon the hollow boring tool can be re-introduced and put into operation. All this is not only cumbersome, but because of the considerable amount of dust that is inevitably discharged to the environment and this dirty to a considerable extent, also annoying and often - such. B. in inhabited rooms - unreasonable. Although are also Diamantkronenboh rer known with water flushing and cooling, but these can certainly not be used in inhabited rooms and especially on wallpapered walls.
  • the invention has for its object to develop a device of the type mentioned so that the breakthrough can be made in one operation without the polluting dust environment.
  • the hollow drilling tool consists of a innenzentri mecanicslosen core drill with respect to the drill sleeve radially inwardly and outwardly projecting cutting teeth and with at least one remote in the region of the drill bit end of the drill sleeve air inlet opening and that the core drill with its sleeve longitudinally displaceable and rotatably but substantially pressure-tight in a hollow chamber sleeve with sealing Wandungsstromrand and is arranged connected to a suction chamber outlet.
  • a cuttings channel which has a hollow cylindrical section extending along the inner lateral surface of the drill sleeve and a hollow cylindrical section extending along the outer lateral surface of the drill sleeve, these two hollow cylindrical sections being connected to one another by the gaps existing between the cutting teeth.
  • the suction device is provided with a filter for collecting the sucked cuttings.
  • the axial forces to be used for drilling are very low, because a centering inner drill is missing and, as a result of the vacuum flushing, no friction occurs between the drill sleeve and the wall. After completion of the drilling process and removal of the device, the cylindrical wall drill core can be removed cleanly.
  • the drill sleeve preferably has a smooth-surfaced inner and outer sheath to promote the transport of the cuttings through the air flow.
  • the measure aims that the centrally mounted cutting teeth have a radial extent corresponding to up to four times the wall thickness of the drill sleeve.
  • the drill sleeve will of course give a length which corresponds at least to the largest thickness of the wall to be drilled; However, in order to avoid unnecessary excess lengths, it is advisable to arrange the air inlet opening or openings in the bottom of the drill sleeve facing away from the drill bit.
  • the core drill can readily be considered an integral part of the Be executed rotary drilling; However, preferred is an embodiment in which the core drill with rear clamping shaft is designed for a chuck of the rotary drill. Moreover, it is recommended that the hollow boring tool and the attached rotary drilling machine, which expediently consists of a rotary impact boring machine, to guide against the hollow chamber sleeve.
  • the hollow chamber sleeve preferably has a guide at least for the drill sleeve; this can advantageously consist of attached to the hollow chamber cuff centering rollers.
  • the hollow chamber sleeve and the drill sleeve are sealed in the simplest case by an on the one hand to the hollow chamber sleeve attached, on the other hand, applied to the drill sleeve annular lip seal against each other.
  • the hollow chamber sleeve is expediently designed as a rigid component, it is recommended to form the sealing Wandungsstromrand of a resilient sealing profile.
  • the sealing profile has a suction cup cross-section.
  • the chamber outlet is expediently designed as a connecting piece for the suction device. If the device for the production of breakthroughs with a particularly large diameter set up and for this reason bulky and unwieldy, it is recommended to provide the hollow chamber sleeve with a chassis.
  • the device operates with a hollow boring tool, which has a drill bit 3 formed by cutting teeth 1 at the free end of a drill sleeve 2 and can be driven by a rotary drill, not shown.
  • the hollow boring tool consists of a innenzentri mecanicslosen core drill 4 with respect to the drill sleeve 2 radially inwardly and outwardly projecting cutting teeth 1.
  • the core drill 4 is longitudinally displaceable with its drilling sleeve 2 and therefore, but arranged substantially pressure-tight in a hollow chamber sleeve 6 with sealing Wandungsstromrand 7 and connectable to a suction chamber outlet 8.
  • the drill sleeve 2 has a smooth-surfaced inner and outer sheath.
  • the centrally mounted cutting teeth 1 have a radial extent, which corresponds approximately to four times the wall thickness of the drill sleeve 2.
  • the air inlet openings 5 are arranged in the drill bit 3 facing away from the bottom 9 of the drill sleeve 2. From the figure it is readily apparent that the core drill 4 is executed with rear clamping shaft 10 for a chuck of the rotary drilling, which is suitably designed as a rotary hammer drill.
  • the hollow chamber sleeve 6 has a guide at least for the drill sleeve 2.
  • the guide initially consists of attached to the hollow chamber sleeve 6 centering rollers 11 for the sleeve 2.
  • Schematically indicated is another guide, namely axial guide 12 for the rotary drill.
  • the hollow chamber sleeve 6 and the sleeve 2 are in any case sealed against each other by a lip seal 13, on the one hand the hollow chamber sleeve 6 is attached and on the other hand bears against the drill sleeve 2.
  • the sealing Wandungsstromrand 7 is formed by a resilient sealing profile with Saugnapfähnlichem cross-section.
  • the chamber connection 8 is designed as a connecting piece.
  • the hollow chamber sleeve 6 is still provided with a chassis, which is not shown in detail.
  • the hollow chamber sleeve 6 is attached with the core drill 4 held therein at the appropriate location on the wall 14. If now the suction device connected to the chamber outlet 8 is put into operation, then the hollow chamber sleeve 6 sucks firmly against the wall 14, whereupon the rotary impact boring machine can be put into operation. It is now in the wall 14 of the core drill 4, a hollow cylindrical recess 15 is generated. The dust released by the cutting teeth 1 is sucked through the air, which flows through the air inlet openings 5 into the drill sleeve 2 and from there into the hollow cylindrical recess 15, via the chamber outlet 8. If the wall 14 completely pierced, the dust-free core 16 can be easily removed.
